Abstract (en)
An intermediate sleeve (30) to be rigidly connected to the end of the motor shaft (11) is provided, having an inner surface (32) of frusto-conical shape adapted to fit the frusto-conical surface (12) of the motor shaft (11), and a cylindrical outer surface (31), and having at least one rib (33), projecting radially from the cylindrical outer surface (31) and positioned to the side thereof; the end of the pump shaft (21) possesses an axial cavity (22) having a cylindrical surface (23) adapted to engage as an exact fit the outer surface (31) of the sleeve (30), and has at least one projecting axial element (25), arranged to lie axially alongside said rib (33) of the intermediate sleeve (30), and to interfere therewith during rotation. There is also provided an intermediate ring (40), which fits onto that axial portion of the sleeve (30) involving said rib (33) and has an annular cavity which surrounds the outer surface of the sleeve (30) and is divided into at least two separate sectors (43a, 43b) by radial baffles (44), of which a first sector (43a) is arranged to receive said rib (33) of the sleeve (30) as an exact fit, and the second sector (43b) is arranged to receive the axial element (25) as an exact fit. <IMAGE>
